A couple of questions here.

 

1. The NatWest form contains only 12 spaces for a tax ID. The newer Thai tax IDs are 13 digits, the old ones are 10 digits plus 3 hyphens. So I entered my old one with no hyphens. Two months later I got a letter saying the format was wrong. Anyone else had this problem and found a solution? Santander didn't complain about it. The Natwest phone number for help on this is busy all day or just rings.

 

2.  The requirements on the form are confusing:

 

"Please provide details for each country where, for the purposes of taxation, the account holder is a tax resident or is a citizen.

Please note: Tax residence relates to where you live, and the citizenship relates to where you were born or the country of your passport. You can be tax resident in one country and a citizen of another."

 

It's the "citizen for the purposes of taxation" I don't get. If I have another citizenship and was tax resident in that country 50 years ago but hold no accounts there, do they want that information?

Some countries (notably the US) consider their nationals potentially taxable forever, regardless of where they live. So that's why NatWest want to know about your citizenship as well as your tax residency.

I just took another look at the latest form and it is different from the first one. The latest form does have 13-digits for a Thai tax ID but instead of asking about tax residency in the current year, it appears to want tax residency for every period.
